Bought the pump from a John Deere dealer, and they are the ones who advised me on the number change. Called there yesterday, parts department didn't't know why the number changed or if I could run the new pump. Service department was closed when I called.
I agree with you. Why would they eliminate the cooling fan. I don't have a problem using it if I could get a reasonable answer why they eliminated the the fan.
Frustrating to spend almost a $1,000.00 and not be the same pump.
